Hi,
I used to use pre-defined rules for a long time now. Today I realized that when I apply the rules, the names of concerned activities are changing to the field 'payment receiver' and the content of the field 'comments' is changing to the field 'name'. I can't remember that this happens before
Is there any way to adjust this? Due to the late discovery even my back-up files are mess up in a way now...

Exactly. I created the rules by myself to categorize the activity automatically by his name (this is the only purpose). And it works quit well in the past with previous versions of iCompta. Using the same rules now creates the described issue. I tested it also with a new rule just for this purpose: the same result.

(Btw: In addition to the described issue: in the now empty field 'comments' appears sometimes 'new transaction')
